[Mate 8 General] jbmc83:
well i wouldnt say "at all", as i said, the powersaver governor does work in restricting the premature ramping up of cpu clocks :)
[Mate 8 General] gthebest:
Today I'm in 7.50 hours SOT and 3% (total using 2 days and 13 hours) by using Kernel Adiutor. I'm in B330 but I'm not satisfied with this SOT. Do I have to use some other ROM e.g. B560 or B190 ?
[Mate 8 General] tunismahdi:
hello to everyone

first of all sorry for my grammar

secondly i'm so despert originly i have the mate 8 NXT-L29C185B200 and it worked fine than i used the ff app to upgrade it to the C185B560 and it worked like a sharme specialy the batery . few days ago i recived the 580 version which claims that they improved the battery but infortenly the was a big lie and the phone wont last a day in a regulare usage.i tried use the ff app but i download the update it wont insatal . so can anyone please help me back to the C185B560 version without rooting.

i'll be so thankful again sorry for the language
[Mate 8 General] jbmc83:
well it also depends on your usage patterns. lots of gaming and gps will drain your battery faster, naturally...
[Mate 8 General] ubermorgan:
Hi guys. Long story short, upgraded my rooted L29 b200 to b560, ruined the phone because update removed google account, keyboard, google voice set to default with not alternatives, removed alarm. Thats when i started frothing at the mouth and downgraded back to b200. Rooted again however i feel the battery life is a little lower than before. i recently downloaded kernel adiutor which i think is cool and im going through the cpu governer. I have set the governer to powersave which may or may not make a difference, i guess i will know in the next few days but im just wondering if setting the maximum frequency to 807mhz will also make a difference?

You guys are pros compared to myself, im affectivley a novice at this stuff so what do you think guys? are the options in the cpu governor enough or could we also play with the frequencies?
[Mate 8 General] gthebest:
I also try to use greenify, and try to freeze Facebook and Chrome. But it's not freeze them all the times. Sometimes I found them running and I must freeze them by myself.

Nougat phone idle drain . Marshmallow battery life is better and smoother ROM
[Mate 8 General] jbmc83:
i tend to disagree, smoothness is best on nougat rom with battery life about the same as marshmallow based on personal experience :)
[Mate 8 General] gthebest:
I'm very confused which rom to choose b330 or b560 ? I'm in b330 and I can't take more than 7,5-8 hours SOT, by using greenify and kernel Adiutor, with total use 2 days and 7 hours.
[Mate 8 General] owhy:

[Mate 8 General] jbmc83:
no idea what you guys are all doing, but my sot still hovers around 10h as always, atm im on nougat B575
[Mate 8 General] apat26:
CN ROM have very good battery life. Even B587. Problem is with C185 Nougat ROM. Both are draining fast....B560 & B580
[Mate 8 General] p51d007:
Something else to consider, if your cell phone signal is not full bars, your battery life could be impacted.

The lower the signal level, the more battery it could use, when it has to boost the output power on the

phone, to keep a lock with a poor signal level.
[Mate 8 General] Dedzdedz:
So i dropped my s7 from the 4th floor 2 dqys ago... endend up buying the mate 8! Great battery life 1 day and a few hours and 5h sot, 18% left, gps, bluetooth, on, 6 hours of spotify, texting and a couple calls. Hopefully it will get better
[Mate 8 General] darkangel0077:
i get nearly 6 hours loaded with apps

little heavy use

all options are on,

but sometimes it awakes alone & shows no app consuming idk why!

a little annoying drain!
[Mate 8 General] Dedzdedz:
Need help...
[Mate 8 General] Dedzdedz:
Discharging too fast
[Mate 8 General] Pfeffernuss:
Why? Around 7 hours of SoT with crappy and battery killing apps like Facebook in the background seems rather normal to me imho :good:
[Mate 8 General] Dedzdedz:
I had to factory reset, there was something wrong, now it feels better.
[Mate 8 General] p51d007:
Glad that took care of it. I wonder if it was a "issue" with the old cache? I had a goofy issue on the 560 build.

If bluetooth was on, and I rebooted, it was off after the reboot, and I had to turn it back on manually. It would stay

on without an issue, until the next time I booted the phone. I went in and deleted the dalvik cache and it appears to

have solved the issue. If bluetooth is on at reboot, it's on after it comes back up.
[Mate 8 General] Dedzdedz:
I'm pretty sure it was the old cache, the previous owner updated to 7.0 and didn't clear cache nor did a factory reset. Now i am able to get 6 to 8 hours SOT and battery does not discharge as it did before! Quite happy now!
[Mate 8 General] childoftheworld:
L29C636B585 (same with L29C636B580) inexplciable crazy battery drain like never before. I used to be able to have around 3% discharge every hour, now it is crazy higher... like going CRAZY. Help!
[Mate 8 General] jbmc83:
have u done a clean install with factory reset? check drain with no apps installed, clean system, all sensors switched off on airplane mode and cpu governor set o powersave. then check again with your apps installed, that way you can determine what is at fault.
[Mate 8 General] saeedbg:
Not good[emoji52]
[Mate 8 General] childoftheworld:
managed to reset twice before... but restored from Google's Backup

Doing a third one to see....

Noticed that after the 3rd one, battery is bad as well.... oh well
[Mate 8 General] jbmc83:
huh? im seeing close to 9h SOT for a full charge including heavy gaming, thats is completely fine!
[Mate 8 General] saeedbg:
in android 6 sot 12.5H in full charge

and 6H in half charge
[Mate 8 General] jbmc83:
identical usage? same apps? same games? same settings? everything exactly the same? ;)
[Mate 8 General] saeedbg:
Yes everything exactly, no game in 7 no Facebook in 7 ,but Battery very weak
[Mate 8 General] MauriceDz:
Did anyone have their battery replaced? I've been seeing my battery run out really fast the past 2+ months, I think it has gradually reached this point. I reckon a new battery would fix this at least 90%, it's been already 1 year of heavy use.
[Mate 8 General] DQEight:
In android 6 ver B170 I got maybe 45% battery loss in 12 hours of normal use (light web browsing, reddit, a little gaming, IM)

In android 7 B563 I am draining battery almost 80% by the same time. Is B580 better on battery or should I not bother?
[Mate 8 General] childoftheworld:
Not any better. I am hoping there is an EMUI 5.1 based on Nougat 7.1.2,

I am on B585 and I am about to die... battery is dead, dead, dead... so dead.!

EMUI 5.0 is Nougat 7.0, heavily bugged... all brands on 7.0 has huge battery drain issues!
[Mate 8 General] K4Y3R:
Can it be possible, that huawei installed a way to force you to use their apps, instead custom ones. Like since the release of the google pixel i liked the launcher, so i recently installed a custom launcher to fix this problem..so far so good. Because huawei sort of cancels the use of the stock widgets in custom launchers i had to go with a custom one too, and suddenly my battery barely lasted 2 days with like 8hrs sot. So i checked the battery tab in settings and there was a enntry for the huawei clock service..so maybe go back to stock would fix this?
[Mate 8 General] saeedbg:
Finally, with power save mode
[Mate 8 General] jirka607:
What apps are you using?
[Mate 8 General] jirka607:
Guys please what is phone idle and autonavi service and why does it drain battery so much?

Thanks

Edit:looks like the autonavi is using lots of battery to me... Anyway to disable it?

EDIT2: can you please check if the drain is normal?

I unplugged phone at 7am now its 6pm and screen time is 2hrs15mins

Thank you
[Mate 8 General] dante-fu:
It is a Chinese alternative to Google location services. Do you have a China ROM?

Try disabling the location information in quick settings, or tune it so it doesn't use GPS.
[Mate 8 General] saeedbg:

[Mate 8 General] jirka607:
Yes i have AL10 model.

Is it true that on MM the battery was better? Because i can easily downgrade via HiSuite?
[Mate 8 General] Apad121:
Hi there

I saw on a post somewhere that someone updated to Nougat on L29C636 and then everything was working aside from the battery life being good. So they decided to do a factory reset on nougat and their phone then became messed up. They were then forced to root their phone.

Is it safe and advisable to factory reset the phone on Nougat?

:)
[Mate 8 General] apat26:
I have factory reset nougat so many times and that too on different regions ROMs, have never even once faced any issue.
[Mate 8 General] Apad121:
Hi there

That's good however which version of the Mate 8 are you using?

I've heard numerous issues with the L29C636 version.

Also could you help me find a link to downgrade back to marshmallow from nougat as I haven't been able to find a post that could help me do that in the future anywhere.

I'm just wondering if I do upgrade to nougat could I still downgrade back to marshmallow without rooting the device...

Thanks
[Mate 8 General] apat26:
That's the one of the version I have not tested L29C636. To rollback, there is a file you need to dload and then dload mm version. You will get that file in one of the post here
[Mate 8 General] aliishmas:

plz help me

l29c185b580
[Mate 8 General] Apad121:
Has this issue happened before? How many times? Could you post a battery graph?

Do you suspect it's the firmware?
[Mate 8 General] cih997:
Hi guys,

B581, rooted, suddenly slowed down without installing any new app (auto updates for apps is enabled though), quick charge is 2-3 times longer, battery drain is very bad (over night 30-50% without touching the phone comparing to max few percents previosuly). BetterBatteryStats shows DeepSleep at normal level ( =most of the time). The only trace is that NFC process takes 8-10% of the battery even if NFC is disabled. I froze that app via TitaniumBackup but it is still "running" based on Consumption Level.

Does anyone experience similar issue - sudden battery drain and slow down without any changes made to the system or apps?

Is factory reset / rom update the only known solution? Can I try something that does not require factory reset? Thanks for advice.

Huawei mate 8 battery

[YOUTUBE][QRCODE][/QRCODE][/YOUTUBE]
[Mate 8 General] :
So the last 2 days i was testing my battery beacuse i noticed a drop of juice on my 2 year old device.

A fully charge 100% to 15% got me to:

24hrs 02mins 59sec Phone without charge.

5hrs 52min 10sec display on time

( i used it heavly the 2 days to see the limit)

I also downloaded a app called "Accubattery" it records how much juice you consumed.

I consumed from 100% to 15% Battery 2579 mAh!

So i think my Battery has only 65% left of his capacity :(

(side note i avoided music and youtube normally my phone isnt able to get this long because i hear a lot of music with it - so this was only whatsapp/threema and web)

edit:

afer a charge the app tells me my batteryhealth is on 3.474mah. so 87%!

im not even sure if the app is great or **** :D:D
[Mate 8 General] jbmc83:
2579 mAh consumed for 85% capacity

= 2579/85= 30,34 mAh per % charge. so your current 100% capacity equals to 3034 mAh or roughly 76% of the original designed 4000 mAh ;)
[Mate 8 General] :
allways amazed from you :b

thanks for the detailed info.

So i think there is no way to get my 24% back without a battery replacement right?

edit: i called huawei its warranty :) I send it in next week :)

i also claimed my white points on the screen - maybe from pressure im not sure. but the chances are good that both get repaired :)
[Mate 8 General] jbmc83:
wow these are great news! i wont be able to do that, since i only got one year warranty on my china imported phone :P

besides, im surprised its covered by warranty at all, since the battery is a "regular wear and tear" kind of item. its normal that over prolonged usage with lots of charging cycles the capacity decreases. think about it: 2 years usage, lets say one charge of 85% every 1.5 days, that equates to 0.57 charge cycles per day. over two years thats 730 days equivalent to 730 x 0.57= 416 cycles! so youve already charged and discharged your battery over 400 times already. that has to show some wear on it!
[Mate 8 General] :
They have to check the phone first ofc. (Um eigenverschulden auszuschliessen) but she said there are rly good chances :)
[Mate 8 General] jbmc83:
cool, keep us updated. curious to see if a new battery is noticeable in sot and overall runtimes :)
[Mate 8 General] Apad121:
Hi there

Just out of curiosity, which os version are you on? Nougat, Marshmallow? And which version specifically like B193/585...

Also hmmm.... Reading the other responses as well... I'm curious to see how accurate this app can possibly be given that it doesn't need root access and it isn't really possible to give a battery capacity given that the mah is not reliably measured and just seem like general guesses... Not all phones consume same amount of power due to different apps open and different os...

?
[Mate 8 General] cih997:
I'll allow myself to answer myself. Wiping cache and dalvik via TWRP solved issue with battery drain and overall smoothness. No factory reset needed :victory:
[Mate 8 General] :
I got replaced my battery and my display. great.

ofc they made a software reset and now im on b582 unrooted, locked bootloader -that kinda sucks ... but i think i wont go to make a rollback and all this... i stay with the orginal rom then :)
[Mate 8 General] gthebest:
Does anyone checked the battery life in new B582 room ? I have the L29C432 version.
[Mate 8 General] mcab95:
Hi guys,

A few months ago I updated to last update available: NXT-L29C432B582.

From that update, the battery life is not the same.

In general, the battery falls faster.

Specifically, under 30% the battery dies almost instantly.

Energy savings or ultra energy savings is useless.

Do you have any suggestions?
[Mate 8 General] jbmc83:
look like your battery is either dead or poorly calibrated...
[Mate 8 General] mcab95:
How can I try to calibrate the battery?

Huawei made me this test:

- Charge battery at 100%

- Airplane mode on

- Disconnect from charge

- After 8 hours, if battery <95% meant it was dying

After test my battery was at 98%. ?

Before update, my battery life was awesome!

I think there is a bug in the update.
[Mate 8 General] jbmc83:
calibration is actually quite straight forward:

https://www.androidpit.com/how-to-calibrate-the-battery-on-your-android-device
[Mate 8 General] Vrykyl:
I'd be very careful to immediately blame the ROM for battery life, mine had been poor for ages (less than 1 hour SoT, maybe 10 hours max off a charger)... Seemingly since updating to the official Android 7.0 based firmwares

Took the plunge just after Christmas and replaced the battery with a brand new one - now back to getting 6-8 hours SoT, and go to bed most days with 40%+ battery left. Thats on the latest C636B589 ota

Tbh at this point in its life I'd be recommending everyone look at a fresh battery, they'll likely all be well past 500+ charges

VERY glad I did mine, I'd considered selling and buying a newer version... No need imo now

How to know which app causes wakeup during sleep?

Data & wifi os on not on root app???
[Mate 8 General] jbmc83:
i dont think that setting switch will make much of a difference though :) what i meant was: being connected to a wifi most of the day helps save battery as opposed to being on a mobile network the whole time. but changing wifi behaviour during sleep wont make much of a difference SOT wise...
[Mate 8 General] loudog3114:
Well I was thinking it could cut down on scree-off battery drain, and lead to maybe getting another 1-2 hours of SOT. Right now b160 seems to, if anything, be far worse at keep android system and android OS at bay. 24% android system and 14% android OS usage at the moment, with 79% battery.
[Mate 8 General] jbmc83:
dont pay so much attention at what percentage android OS and its usage are burning through.... they change depending on your app usage and overall usage pattern. what matters in the end is the SOT ure getting :)
[Mate 8 General] :
42 Hrs from 100-11%

GPS&Wifi always on.

Brightness Auto

SOT = 5Std30. (with youtube)

All things are without Trickstermod or anything. Just Stock.

Now ill try the same with Trickstermod and LuxDash. Update soon ;)
[Mate 8 General] jbmc83:
switch off GPS when u dont need it. either that or switch to low power mode (via networks, not GPS module), thatll save u tons of battery life!

wifi is pretty frugal, doesnt take up much energy. still, i only switch it on when needed :)
[Mate 8 General] icy20:
Hello guys! From today I will be doing my regular usage of my mate8. I had some problems since I changed from chinese firmware to international one but with the help of jbmc83 I solved it! Do you guys use any tricks in order to enhance battery life? https://play.google.com/store/apps/details?id=com.bigeyes0x0.trickstermod&hl=en <- This is the mod that some of you talked about? Does it do any difference? If it does what have you changed with it? My usage is like this: I'm out with a car going to support customers with all functions on except 4g (3g is enough for me) of course since I am out the sunlight doesn't help to conserve energy. I also talk a bit (1-2 hours by bluetooth which is always enabled and connected).
[Mate 8 General] jbmc83:
just answered you in the antutu benchmark thread :)
[Mate 8 General] Wartoon:
Someone tried Greenify? How is the battery-life with this app?
[Mate 8 General] icy20:
Yep I use it. It hibernates the apps but sometimes they wake up by themselves and I don't know why. But if I remember correctly it did the same thing to my Xperia Z3...
[Mate 8 General] jbmc83:
thats weird, im using greenify as well but there is nothing to hibernate, because the system already does that very efficiently once u close an app. every time i press on my hibernation homescreen shortcut it says theres nothing to hibernate :D vastly different from my previous nexus 5, where the apps still had to be greenified even after uve closed them. admittedly, that was also still on 5.1.1 lollipop...
[Mate 8 General] loudog3114:
Personally, I wouldn't. It would only interfere with the already extremely aggressive smart battery mode. In fact, the stock huawei software does a better job than any phone I have had with greenify/wld.
[Mate 8 General] icy20:
Obviously u have enabled autoclose of powerhungry apps from the phone manager?
[Mate 8 General] Wartoon:
Thx guys, so my only problem is that wakelockdetector says, my phone is 30 awake and i think that's to much ;) my oneplus one was only 2 or 3 % awake with Greenify.

---------- Post added at 07:38 PM ---------- Previous post was at 07:37 PM ----------

Someone tried to get more battery-life by deactivating the fingerprintreader?
[Mate 8 General] jbmc83:
um...no. i dont think thats the problem though... sounds more like one of ur apps might be force keeping the system awake...
[Mate 8 General] :
Without Trickstermod i loose 4% in one Night.

With Trickstermod i loose 1%;)

Oh btw is it normal that trickstermod resets itself aftee a reboot?
[Mate 8 General] icy20:
Since I have not done it yet, do you guys with trickstermod active @ powersaver governor see reduced performance like stuttering or lag when using the device at everyday use?
[Mate 8 General] jbmc83:
nice, good to see it really DOES help ;) probably one of the reason why in getting 10-12h sot :D

[MENTION=1614188]icy20[/MENTION]: no stuttering here in everyday usage, but then again, it depends on your usage of course :) the cpu still clocks up, just way more seldom.

and yes, it resets itself with each boot, unless u specify to apply the settings at boot! tap the settings button on the upper right corner (left button of the two) and set all four check marks:
[Mate 8 General] icy20:
Good. I set it to powersaver. Let's see... I added trickstermod to the trusted apps that work with screen off. Or is that not necessary?

PS. I saw that max frequency at freq lock is 1.8 ghz. I thought the A72 cores were 2.2 max or something...
[Mate 8 General] jbmc83:
i do that to make sure it applies on boot :) it doesnt consume any power whatsoever afterwards, just needs to apply the settings and thats it! keep us updated on how your experience is on powersaver!
[Mate 8 General] :
THX again, buddy.
[Mate 8 General] icy20:
Do you change any other setting except governor? Or everything else as they are by default? Do u know what happens with the frequency lock i mentioned above?
[Mate 8 General] jbmc83:
ive played around with the other settings, but most of them dont stick, since were still on a stock kernel. we would need a custom kernel to use all settings possible :)

same goes for the frequency lock, once u change anything it just reverts back to stock, so no use to do anything there. as for the read clocks, i think trickster mod can only read the clocks of the smaller A57 cores that clock up to 1.8 ghz. the larger A72 cores in the Kirin 950 octacore can do up to 2.2-2.3 Ghz :)
[Mate 8 General] icy20:
That would make sense...
